i AUXILIARY BLOW-OFF AND WATER-INLET FOR LOCOMOTIVE-IBOILERS.

Specification of Letters Patent Patented Dec. 31, 1918.

Application filed 0ctober 18, 1917. Serial No. 197,315.

To all whom it may concern:

Be it known that I, JOHN L. Goon, a citizen of the United States, and a resident of Horton, in the county of Brown and State of Kansas, have invented certain new and useful Improvements in Auxiliary Blow- Otfs and \Vater-Inlets for Locomotive-Boilers, of which the following is a specification.

The present invention relates to an attachment for locomotives and the like, and has for an object to provide an attachment for facilitating the exhaust of steam and smoke from the locomotive when stationed in round-houses and the like.

It is the present practice to run locomotives into round-houses beneath smokejacks or fines which conduct smoke and gases through the roof of the roundhouse to prevent accumulation of smoke and gases therein.

It is also the present practice, when it is desired to exhaust all steam from the boiler of the locomotive, to attach a length of pipe to the steam chest or other convenient lace of attachment and open the throttle o the locomotive for exhausting steam from the boiler through the various devices connected to the locomotive and out through the pipe to the exterior of the rounolhouse. Considerable time is required in attaching this pipe to the locomotive and furthermore steam is permitted to escape through the various joints and-connections uniting the parts of the locomotive through which the exhausting steam is conducted. This exhausting steam soon fills the roundhouse andprevents access of workmen to the various parts of the locomotive to repair the same. Furthermore, the attached pipe obstructs the pas-' sages about the locomotive and materially interferes with the carrying on of work in the roundhouse. Further, the smoke and gases passing upwardly through the stack of the locomotive do not always pass up through the jack or exhaust pipe in the roof of the roundhouse and thus quickly fill the roundhouse and interfere with the carrying on of the work therein. v

It is the purpose of the present invention to provide a relatively simply constructed and applied device for a locomotive to take care of thesetwo conditions and overcome the disadvantages found.

Various other objects and advantages of this invention'will be in part described, and

from the stack of the locomotive,

'seat, and also to deliver edto. lie close against in part understood, from the following detailed description of the resent preferred embodiment, the sam being illustrated in the accompanying drawing wherein- Figure 1' is a side elevation o. the front end of a locomotive arranged beneath a smoke-jack and being partly broken away, showing the attachment of this invention applied to the locomotive.

Fig. 2 is a side elevation, partly in section, of the steam andsmoke exhausting device of this invention, the view being enlarged.

Fig. 3 is a further enlarged sectional view through the upper end of the device of this invention, showing the removable closure 021% which may be employed.

eferring to this drawing, A designates the boiler of a locomotive, B the smoke box thereof upwardly from which leads the smoke-stack C, and D jack or exhaust pipe such as is usually employed in the roofs of round-houses and the likefor conducting smoke and gases directly from the stack C through the roof of the round house.

The device ofthis invention comprises a pipe which is composed of a connecting section 10 and an exhaust section 11. As shown in Fig. 2, the connecting section 10 preferably comprises a pair of nipples secured to. the opposite ends of the interposed valve 12, the valve controlling the passage of steam or other fluil through the connecting section. The lower end of the section 10 is adapted for attachment. dir. ctly through the upper wall of the boiler -t, adjacent the front tube sheet 20 thereof, to receive steam directly from the boiler adjacent the stack water or the like, directly into the boiler. The valve 12 is provided with a handle 13 which preferably projects forwardly from the connecting section 10, and which is within easy access of a workman when it is desired to open the valve. i

The upper end of the connecting section 10 is secured to one end of a T-coupling ll the upper end of which isclosed by a removable plug 15 and the shank or lateral portion thereof having connection with the exhaust section 11 through pipe 16 and elbow 17. The exhausting section 11 isadaptthe rear side of the held in such position stack C, and may be hand 18 surrounding by means of a strap or the stack C and engaging the exhausting plane of the upper open end of the stack andis aranged in position .to provide an unobstructed passage of steam upwardly from. the open end of the exhausting section 11."

The exhausting section 11 is so located to dispose the exhausting section as well as the old stack C'beneath'the smoke-jack D when the locomotive is brought to its usual position 111 the roundhouse.

After an engine is brought into the roundhouse beneath the jack D, and it is found that thesmoke and gases do not pas freely through the jack D, it is only necessary to openthe valve 12 to the desired extent for projecting steam upwardly into the jack D motive.

valve 12 to the desired extent so as to allow and thus creating a draft which readily carries off all the smoke'and gases.

When it is. desired to blow off the boiler 1t is unnecessary to employ the usual exhaust pipe and connect it in the usual manner to the steam chest or other part'of the loco- It isonly necessary to open the the steam to blow off directlyfrom the boiler and up through the jack In this manner it is unnecessary to open the throttle and thus the steam is not permitted to escape through the'various connection's,-the cylinders, packing boxes and the like, as is usual.

'.- The roundhouse is thus kept free from steam as thelat-ter is directed upwardly into the jack D. through the exhausting section 11- ofthe device. The useof this device, does not only maintain the atmosphere withinthe roundhouse clear and in a healthy condition, but it also reduces the length of time required forexhausting a boiler as considerable time isnecessary for' connecting the us- I nal exhaustpipe and adjusting it to a windew or thelike through'which the steam may be exhausted."

If desired, the exhausting section 11 may be provided with external screw-threads at its upper end for. the reception of a closure trap 19,- the trap being employed when it is desired to press the joint of the pipe, and

when it is desired to introduce water into the boiler throughtheT-coupling 14 by the retit? moval of the plug 1 5.-

I The plug 15 being located at the top of the connecting section 10 admits of the ready removal of the plug when the boiler is under pressure as the valve doors may be closed and all danger'of burning the workmen by exhausting steam is thus overcome. When the Water connection is made with the nipples 14:, the valve 12 may then be opened and the water under suitable pressure may be projected into the boiler A. It is therefore unnecessary to remove the plugs located within the cab as is now the general practice.

By the useof the present invention a first draft is created upwardly through the jack cifically described embodiment of this invention without departing from the spirit thereof to adaptthe device to various conditions met with in locomotive construction, such changes and modifications being restricted only by thescope of the following claims: 4

- What is claimed is: V

1. The combination with a locomotive having the usual boiler and a smoke stack adapted to be centered under a smoke outlet when the locomotive is in a round house or the like, of a blow-ofi device opening into the upper portion of the boiler-adjacentthe front tube sheet thereof and opening at its other end in proximity to the upper portion offthe stack for directlydischarging steam through the smoke outlet from the top of the boiler to the exclusion of the throttle and other parts of the locomotive, and a controlling valve in the device adapted to be manipulated for blowing off steam from the boiler without the use oftemporary fittings.

2. The combination with a locomotive having the usual boiler and a smoke stack adapted to be centered under ai moke outlet when the locomotive is in a round house or the like, of a connecting pipe sect-ion tapped into the top ofthe boiler near the smoke stack and rising directly from the boiler, a T-couphng connected by one arm to the upper end of the connecting pipe section, a removable plug in the other arm of the T- couphng adapted to be removed for introducing water into the boiler, an exhausting pipe sect on extending upwardly against one side of .the smoke stack, a pipe section leadlng from the shank of the coupling to the exhausting section, and a controlling valve interposed 1n the connecting pipe section below the T-coupling.
